The Mendix App Platform consists of 3 parts: - The Mendix Business Modeler (for modeling apps on your workstation) - The Mendix Windows Service (for running apps on your server) - The Mendix Online Platform (for social collaboration)
Running the Mendix Business Modeler on a Windows Server 2008 R2 is unfortunately not possible.

If you would like to run your application on a windows server you should use the Mendix Windows Service 4.0, available through the App Store.
